I have a Lowrance HDS Gen 3 with structure scan, but I never bought a card for it.  Which is the best map card to buy for it?  While I spend a lot of time on Private Waters, I'm surrounded by some great lakes and would like to have more map info for those public lakes.  What do you suggest and why?

hi bruce, i not only fish Private Waters, i have fished  many lakes and Lake fork since it opened, and have tried a few map cards in my life.. for my Lowrance i have found Fishing Hot Spots to be the best for my use.. it shows areas of stumps and many details that the others dont show.. one last thing, as with all cards check with the maker to make sure the lakes you will be fishing are loaded on their cards.. i havent been to a lake yet that my Fishing Hot Spots Pro card didnt have.. good luck

Thank you for the recommendation!
